Hi lilamn,
Thanks for the response.
I fix the problem, I move canti.properties from system32 to the root folder of Canti, and restart my computer.
First, I thought it crashed because I run windows 64 bits, but I think it got me a nullpointerexception because it cannot find "canti.properties" file.
Your program is awesome

You don't want to rewrite it in C# with a good Gui ?
